What I realised later was that Sitosfe was hitting the bug in libdrm-intel that was causing it to fallback to swrast. After applying that patch, you also need libdrm-intel-2.4.41 or just http://cgit.freedesktop.org/mesa/drm/commit/?id=fdda97007b1dbf95beb16a0e3510fd36c89e8c33

Paul, can you update libdrm and see if the bug returns?
